HOOP-MACHINE.

SPECIFICATION forming part of Letters Patent No. 241,928, dated May 24, 1881.

' Application filed October 18, 1880. (No model.)

To all whom it may concern Be it known that I, CRowELL M. OLANGY, of Wallaceburg, Kent county, and Dominion of Canada, have invented an Improvement in Hoop-Machines, of which the following. is a specification.

My invention relates to improvements in hoop-machines; and it consists in the peculiar construction and arrangement of the parts, as herein more fully set forth.

In the drawings, Figure l is a side elevation of my improvement. Fig. 2is a section on the line a w in Fig. 1. Fig. 3 is a plan view of the bottom, taken on the line y y in Fig. I. Fig. 4. is a detached plan view of the horizontallycutting knife with its attachments. represents the manner of operating the three knives.

In the accompanying drawings, which form a part of this specification, A B 0 represent a suitable frame to support and carry the operating parts of the device. To the lower part of the frame is journaled the main shaft D, to which motion may be communicated from any suitable source. To each end of this main shaft D are secured the eccentrics E F, which, by means of suitable connecting-rods, G, give an alternate reciprocating motion to the crossheads H I, carrying the knives J K. These cross-heads have their motion upon the slides L M, suitably secured to a support, N.

0 represents a table, upon which the material to be cut is placed and P is a feed-guide, by means of which the plank or cantis fed to the operating-knives, and this feed may be actuated by any of the known mechanical devices in use for giving an intermittent motion thereto, as may be desired.

The machine constructed as above described is all that is required in cutting hoops from a plank having a thickness equal to the width of the hoop desired. The plank being placed upon the table and fed up to the point for cutting, the knife J, having a diagonal cut to give the required bevel, (and this knife should be adjustable to any desired bevel,) makes its first out, being actuated thereto by the eccentric movement from the main shaft D, and on this knife receding from its out, having left a Fig. 5-

beveled edge to the plank, the knife K makes its vertical cut, the plank having been fed up the proper distance, thereby severing the second hoop, and so on, the knives giving an alternating vertical and diagonal out until the plank is used up.

Where it is designed to cut bevel hoops from a cant the eccentrics E F are so set as to limit the throw of the knives J K to the width of the hoop desired, and the cant being in position on the table the operation of cutting the hoops is commenced in the manner already described; but in order to finish such hoops, by cutting them from the cant at the bottom of the stroke of the knives which cut the straight and bevel sides thereof, requires additional mechanical devices for operating a knife having a horizontal cut in oscillating lines at the base of the cuts which, form the sides of the hoops. To accomplish this end a spur-wheel, Q, upon the main shaft D gives motion to the counter-shaft S through the spurwheel R. Upon or near the end of this countershaft S is secured the bevel-pinion T, which gives motion to a like wheel, U, upon the vertical shaft V, suitably journaled to the side of the frame. Upon the top of this shaft V is secured the wheel W, to which the horizontally-actin g knife X is adjustably secured by means of the slot a and wrist-pin b. A similar arrangement at the opposite side of the frame may be provided to give motion to the opposite end of the knife, the two wrist-pins being so arranged as to give a horizontallyoscillating motion to the knife; or such motion may be obtained by one connection, as described, and the opposite end of the knife by means of the curved slot 0 engaging with the stud d.

By this arrangement, after the knives have cut the sides of the hoops, the knifeXis thrown forward horizontally to out such hoops off at their bottom edges, the oscillating movement described giving a drawing-cut to the knife.

What I claim as my invention is- 1. The combination, with the shaft D, provided with the eccentrics E F, of the slides L M, cross-heads H I, knives J K, set at an inclination to each other, as described, and

connecting-rods G, whereby an alternate reciproeziting motion is given the knives, substantially as described.

2. The combination, with the shaft I), pro- 5 vided with the eccentrics E F, and spur-wheel Q, of the slides L M, cross-heads II I, knives J K, counter-shaft S, having spur-wheel R and bevel-pinion T, shaft carrying the bevel- I for the purpose set forth.
